Further implementation of SPIRV direct emit. (#1920)

* Further implementation of SPIRV direct emit.

This change implements:
- Struct, Vector, Matrix and Unsized Array types.
- Basic arithmetic opcodes, vector construct, swizzle etc.
- getElementPtr, getElement, fieldAddress, extractField.
- SPIRV target intrinsics with SPIRV asm code in stdlib.
- RWStructuredBuffer and StructuredBuffer.
- Pointer storage class propagation.
- Control flow.

* Fix.
